This is a person, man or woman who walks around like they are the shit. This person is an overblown braggart who believes in themselves like some people believe in God. This person is recognized by exaggerated stateliness; and oh so pretentious in speech and manner.
Here comes Dominic again, "sigh" man that guy is one rooty toot insecure mother fucker!

Real as it can be, never actually seen a RMF (Real Mother Fucker); just like they say, inscrutable, volatile, a bit tricky to deal with.
